' Be it known that LCURT KU NTZEL, a

V 7 subject of William 11, Emperor of Germany,

residing at Youngstown, in the county 0 -Mahoning and State of Ohio,-h W invented new and" useful Improvements in Stock- Racks for'Tire-BuildingMachines, of which the following isa specification;

This invention relates to stock racks for use in connection with tlre-buildlng-ma- B'riefly,'it is important that in building tires, especially ipneumatic: tires, that a source of supply of tire-building material be positioned conveniently tothe tire build- 1 ing machine, so as to render the operation of the bulldmg of-the' tl're easier and more f Winding of fabric with thethreads disposed.

quickly accomplished.- Also it is frequently necessary in the building of pneumatic tires andhence, the easiest way bywhich this can be accomplished is to have two vstock rollers conveniently placed, one of which carrles a in one direction and. a second stock 'roller with the threads of the fabric or tire-building material disposed at an angle" to the threads of the fabric onthe first roll. f

Therefore, the object of this invention is to provide a simple and compact device for stock rollsfconveniently placed and support- "ed forready use adjacent to a tiresbuilding- With the foregoing and other objects in view, the invention consistsin the novel con.-

of a guidingrojller employed; and,

Fig. 6,-is a transverse section of Fig. 5 takenonline Y.

Referring to the drawings in detail, the reference numerals 1 and 2 designate bases suitably mounted von any convenient support, such for instance, as. a floor. Extending upwardly from the bases 1 and 2 are a pair of uprights3 and 4: which are both provided with longitudinal, parallel and inwardlythat the threads of one layer of tire-building material must bed'isposed at an angle with -respect to the threads of a coadjacent layer,

extending ribs 5 and 6. The upper ends of the members 8 and 4 are connected and held against movement and in. parallelism through the medium of a cross-bar 7 on the for thevertical reciprocation of a carriage which consists of a pair of similar side members 15 and 16 the outer faces of which are provided with longitudinal grooves to receive the ribs 5 and 6. The upper ends of the members 15 and 16 are connected by a cross bar-17 andthe lower ends by a cross bar-.18 so as to form .a hollow rectangular "member. The side bar 15 is provided with a series of spaced openings 19 arranged in verrage ismoved vertically to besuccessively brought into transverse registration with the opening 10 in the member 3, Mounted on the carriage are a plurality of stock rolls and tension devices for tire-build ing material and as they are all similar, a description of one is believedto be sufficient for the understanding of them all. Onthe rear faces of the uprights 15 and '16 are a pair of rearwardly-extending, upwardly-iaelined slotted brack ts 20, The

slots 21 constitute-bearings for the end spinlayers of sticky tire-building material from adhering together. The slots 21 also constitute bearings to receive the splndle ends'24 of a take-up roller 25 onto which the strip.

of muslin winds as the tire-building material is unwound from the roll 23.

Positioned below the stock roll 23 in suitable openings in the uprights 15 and 16 and in horizontal alinement with each other is a pair of journals 66 and 67 (see F igs.5 and 6'). These journals 66 and 67 project inwardly toward each other beyond the inner faces of the members 15 and 16 and constltute supports for a pair of rods 68 arcuate in cross-section and extending between the members 15 and V 16 and slightly spaced apart. Mounted in suitable openings in the journals 66 and 67 is a shaft 69 one end 70 of which is squared to receive awrench and the portions of the shaftbetween the bearings 66 and 67 are provided with reverse threads 71. A collar 72 holds the shaft from transverse movement. Mounted on the shaft 69 are a pair of guiding members i 7 3. each interiorly and reversely threaded with respect to one another so that by the rotation of the shaft 69 they'will be drawn toward or away from each other. These guides 73 are provided with apertures to receive arcuate rods 68 slidable. thereon land are held from independent rotation a on one bracket 27. This pin 32 also bears a rocking-arm 33, on the outer end of which is a pin 34 loosely connected with the 'opposite end of the brake-band 31. Pivotally secured to the pin 341is a counterweight 35. Revolubly mounted in the projecting ends of the brackets 27 is a smoothing roller 36 having a greater diameter at its transverse median portion than at its ends and with 7 its outer surface tapered in both directions and provided with reversely-arranged helical grooves 37.

Positioned adjacent .to the device is a cylinder 38 provided with a reciprocating piston (not shown) adapted to be operated by any suitable fluid. The piston bears a piston-rod 39 onthe upper end of which is revolubly mounted a plurality ofsheaves BEST AvAaaeLE coPY 40. Extending from a suitable anchorage on the bracket 13 around the sheaves 40 and 14 and from thenceupwardly over the sheaves 12 and 9 is a flexible member such, for instance, as a cord or-cable 41. Communicating with the upper portion of the cylinder 38 above the piston is a duct 42 the upper end of which is connected with avalve casing 43 (see Fig. 4) provided with an inlet port 44 and an exhaust port 45. "Within the valve casing 43 is a three-way valve having a transverse opening 46 and a connecting branch outlet 47. The valve is V operated by an arm 48 to which is pivotally connected a locking arm=49 bearing a pin 50. The locking arm 49 is slidably mounted in the opening 10 in the standard 3. Pivotally secured to thestandard 3 on a bracket "51 1s a bell-crank lever 52 provided at its upper end with a slot" for receiving the pin 59 and at the other end pivotally connected with a rod 53 bearing a collar '54. The rod "53 passes through a guide 55 and between i the guide 55 and the collar 54 is a coiled spring 56 the normal tendency of which is V to raise'the rod 53 and thereby shift the locking arm inwardly or to the right in Fig. 4. The lower end of the rod 53 is pivotally 57 fulcrumed at 5'8. Positioned in front of and in substantial alinement with the upright 3 is a housing 60 provided at its upper end with a journal-box 61 to receive a horizontal shaft 62 which bears a chuck 63 of ordinary construction provided with three radially-extending arms 64 adapted to temporarily hold a tire-building core "65. The core 65 is positioned centrally and in front of the side members 15 and 16 of the carnage.

The operation of the device is asfollows: In order to lower the carriage, the foot-lever 57 is partially depressed which withdraws the locking arm 49 from the respective opening. 19 which is in registration with the opening 10 in the upright 3, and this movement of the locking arm 49 rotates the valve so as to bring the port-46 therein in alinement with the outlet 45 and the branch port 47 1n alinement with the duct 42 which permits connected with a suitably placed foot-lever V the escape of the fluid about the piston out- Ji determined point which is ascertained by the registration of'any one of the openings. 19 with the openlng 10, then the pressure upon the foot-lever is removed and the carriage is u locked in position. I When it is desiredv to ralsethe carriage, the foot-lever 57 is forced completely down, which also removes the arm 49 from the opening 19 and brings the port 46 in the valve into registration with the lnlet 44 and duct 42, allowing fiuid to enter the cylinder, thereby depressing the-pis- BEST AVAILABLE COPY Iton and hence,iraising the carriage through the medium of the flexib'le member L1,
